• Analog output terminal check
When the front cover is removed, the analog output check terminals
(pad: CH+, CH–) are visible at the upper part of the display sub-
strate. The analog output can be checked during measurement
mode or loop check by applying a probe such as a tester for current
measurement, onto the check terminal of the substrate, as shown in
the following figure. In addition, receivers are not affected.
